Help Topical Steroid Weening

I’ve been on triamcinolone .01% for my whole life (20F) and I was using them everyday for a long period in junior high and high school, now I try to use it every other day. I am allergic to almost everything (lotion, skincare products, even body washes and hair products) but I haven’t been able to get chemical allergy testing because I can’t use the cream for 2+ weeks and I start showing signs of TSW. It was miserable and after three weeks I had to start using them again.

I mostly need advice on how to start weening off from them completely. I’m aware that i’m most definitely going to go through TSW so that doesn’t concern me, I am on Dupixent (3ish months) so i’m hoping maybe that will help aid in the process. Any and all advice would be very helpful, thanks!
